RIFLE-CLEANING CARTRIDGE.

Specification of Letters Patent.

Patented June 26, 1917.

Application filed November 20, 1916. Serial N 0. 132,381.

To all whom it may concern:

Be it known that I, LISLE C. WILLIAMS, a citizen of the United States, residing at Helena, in the county of Lewis and Clark, State of- Montana, have invented certain new and useful Improvements in Rifle- Cleaning Cartridges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in cleaning and lubricating devices, and particularly to devices used for cleaning the barrels of rifles and guns,

One object of the present invention is to provide a simple and novel device which is arranged to be fired through the barrel of the rifie, in the same manner as the ordinary bullet, but with the efi'ect that the interior of the barrel will be effectively cleaned by the passage of the projectile therethrough.

Another object is to provide a device of this character whereby the cleaning material carried by the projectile will be held in proper position in operation, but will efiectively expand to engage the interior surface of the barrel.

Other objects and advantages will be apparent from the following description when accompanying drawing.

In the drawing:

Figure 1 is an elevation of a cartridge made in accordance with my invention.

Fig. 2 is a longitudinal sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2.

Fig. l is perspective view of the projectile removed from the shell.

Referring particularly to the accompanying drawing 10 represents a shell which is formed of any suitable material, but prefer-' ably metal, and of a shape similar to that used in the ordinary metallic cartridge shells now used. In the rear end, or closed end of member, an inner disk the shell, there is disposed a charge of explosive material 11, which is adapted to force the projectile 12 from the shell. Directly is disposed a lead or other Embedded in the center of this plug is the enlarged end 14' of a stem 14, WhlCll extends longitudinally through the center of the shell. The other, or outer enlarged end 14 of this stem is embedded in the center of the projectile 12. The projectile 12 is secured in the outer, or open end of the shell in the usual manner, and fillin the space, in the shell between the projectii andthe plug, and surrounding the stem which connects them, is a mass 0 terial is preferably of cotton waste, other similar material which can be packed in the shell to a highly compressed degree, so that it will freely expand within the barrel of the rifle or gun, when the projectile leaves the shell and passes through the barrel. The cleaning material will thus frictionally bear on the interior face of the bar rel and remove the carbon or other matter which might collect on the said surface or Within the rifiing of the barrel.

What is claimed is:

The combination with a cartridge shell, of a gun barrel cleaning projectile located in the shell and including a tapering outer member disposed in spaced relation to the rear of the tapering member and arranged to receive the explosion of the charge of powder in the shell, a connecting and spaclng stem having enlarged ends embedded centrally in the tapering member and in the disk member, and an expansible fabric disposed around the stem and between the tapering member and the disk member.

In testimony whereof, I affix my signature, in the presence of two witnesses.
